Who is this lad and what has he done with Josh Peacock?

Sharper eyes than mine picked up something on last night's Coronation Street that, when I looked again this morning, proved spot on. The little boy who played Josh Peacock was not child actor Ben Beresford. Have we had a recast or was Ben temporarily unavailable? Inquiring minds want to know. Oh gosh! Maybe we've had another Corrie baby switch, back when Josh was in hospital after his allergy attack!
